Robins SG 5.1 Seat and Guide Machine is a specialized piece of equipment used in the automotive and engine rebuilding industry. Its primary function is to recondition and restore valve seats and valve guides in cylinder heads.
Robins SG 5.1 utilizes a number of features to ensure high accuracy. It often incorporates precision carbide centering pilots and a lightweight "air float" workhead, which allows for perfect alignment with the valve guide. This precision results in very tight tolerances, with valve seat roundness and concentricity measured in micrometers. SG 5.1 includes features like "spring-free tooling" and "constant varying speed" to assist in the machining process. It's also capable of threading and tapping.
